Abstract

Purpose

The purpose of this research is to show significant points which can be used in the architectural design process by investigating the basic principles of earthquake resistant design (ERD) in a deductive format and to contribute to the architectural perception in ERD.

Design/methodology/approach

First, the structural irregularity types are examined depending on the rules defined in the Turkish Earthquake Code, 2007 (TEC). Then, architectural design failures related to earthquake resistance of buildings under earthquake loading are visualized and solution suggestions in literature are described in detail by supported drawings.

Findings

The problems causing structural irregularities are investigated deeply with given solutions in literature. It is obtained that the significant factors affecting the earthquake performance of structures are: architectural form, structural configuration, slenderness ratio, the location and rate of floor openings, projection rates and symmetry, rigidity and strength differences between floors, short columns, pounding effect. Social implications – The practical design decision rules can contribute to the phenomena of earthquake resistant architectural design and can encourage adoption of these rules in building industry.

Originality/value

This study aims to gain an understanding of the problems in projects in terms of structural irregularities, and then manage to solve the problems using problem‐oriented approaches. The suggested solutions can be adopted and applied to future projects for designing earthquake resistant buildings.
